This study aimed to investigate the uptake, translocation, and subcellular distribution of chlorantraniliprole (Cap) and tetrachlorantraniliprole (Tca) in maize (Zea mays L.) plants using a hydroponic experiment. Tca mainly accumulated in the roots and stems, while Cap showed better acropetal translocation capacity than Tca. The uptake of Cap was positively correlated with Tca uptake, particularly at the effect of plant transpiration force. Transpiration inhibitor treatments significantly reduced the acropetal translocation of Cap and Tca. The absorption of Cap and Tca in the dead and fresh roots showed a good linear relationship and mainly occurred via the apoplastic pathway. Regarding subcellular distribution, the cell wall was the dominant storage compartment for Cap and Tca. In the protoplast, Cap mainly accumulated in cell soluble fractions, while Tca accumulated in the organelles. This study provides information for the accurate application of maize pest management and is of great significance to environmental risk and food safety assessments.

Indocyanine green (ICG) is a well-established near-infrared dye which has been used clinically for several decades. Recently, it has been utilised for fluorescence-guided surgery in a range of solid cancer types, including sarcoma, with the aim of reducing the positive margin rate. The increased uptake and retention of ICG within tumours, compared with normal tissue, gives surgeons a visual reference to aid resection when viewed through a near-infrared camera.

Selenium and boron can alleviate lead (Pb) toxicity in plants, but their stress resistance mechanisms in tobacco remain unclear. The aim of this study was to investigate the effects of Se/B application on lead-induced oxidative stress, subcellular distribution, cell wall properties, and Pb accumulation. Additionally, a comprehensive analysis of transcriptomics and metabolomics data was conducted.

Immunoelectron Microscopy (IEM) is a technique that combines specific immunolabeling with high-resolution electron microscopic imaging to achieve precise spatial localization of biomolecules at the subcellular scale (< 10 nm) by using high-electron-density markers such as colloidal gold and quantum dots. As a core tool for analyzing the distribution of proteins, organelle interactions, and localization of disease pathology markers, it has irreplaceable value, especially in synapse research, pathogen-host interaction mechanism, and tumor microenvironment analysis. According to the differences in labeling sequence and sample processing, the IEM technology system can be divided into two categories: the first is pre-embedding labeling, which optimizes the labeling efficiency through the pre-exposure of antigenic epitopes and is especially suitable for the detection of low-abundance and sensitive antigens; the second is post-embedding labeling, which relies on the low-temperature resin embedding (e.

Hormones are important bioactive molecules that regulate the development, function, and homeostasis of tissues/organs via binding to hormone receptors (HRs) in target cells. Although human HRs are essential for both basic research and drug development, a comprehensive analysis of them is still lacking. Here, we present a systematic bioinformatic investigation of all known human HRs, characterizing their genomic distributions, biological functions, subcellular localizations, and expression patterns in various cell types and tissues/organs.

Swirling motion is an essential phenomenon that significantly influences numerous biological processes, such as the mixing of molecular components within living cells, nutrient transport, the structural changes of the cytoskeletons of contractile cells and the rearrangement of multicellular systems caused by collective cell migration. The dynamical relationship between subcellular and supracellular rearrangements enhances cell migration and contributes to tissue homeostasis. However, the basic mechanisms that drive swirling motion in biological contexts remain a matter of ongoing inquiry.
